Re: Vacuum Leak
Depends on how bad the leak is. A small leak often won't have enough flow to affect anything unless it's at idle, etc. If the leak is in a hose going to the wastegate, it can easily affect something because the leak will usually be fairly large compared to the small size of the hose.
So what I'm trying to say is that it depends on where the leak is and how bad it is, and under what conditions..

Re: Vacuum Leak
Boost limiter on chip? Rev limiter on chip?
May be a bad ECU. I've had something similar happen and have had it happen to friends too. One thing me and my friends had in common was when in 5th gear at highway cruising speed, if you punch your foot on the accelerator and it stutters/stumbles, it's probably the ECU.
Don't know what kind of car you have, but this has been the case on Hondas for me.

Re: Vacuum Leak
It may or may not. Correct me if I'm wrong, but it is the ECU that illuminates the CEL for any errors in the first place. If the ECU does not know that it, itself, is malfunctioning, it won't throw a check engine light.
